Poskytují velkou variabilitu díky malé tloušťce a nenáročné instalaci (žádné kotle, topná tělesa, potrubí). Díky plošnému pokrytí, rychlosti náběhu a and precise control, maximum comfort is achieved They do not cause dust to swirl or air to dry. They can function as the main or as an additional heat source. The ideal ecological solution in combination with photovoltaics and home batteries.

The disadvantage of carbon heating Film technology is the need for a larger main circuit breaker, which is solvable. In general, for family houses in which the heated area is up to 260 m2, the benefits clearly outweigh the disadvantages.

Innovative compared to heating mats

Area-wide heating

LARX Carbon Kit really heats the whole area. A heating cable or heating mat is only a linear heating element. Therefore, even with the best arrangement of the heating cable or mat, the temperature distribution in the floor will never be as good as with the LARX Carbon Kit.

Savings due to more efficient heat transfer

LARX Carbon Kit has contact with the entire area of the floor covering. As a result, temperature distribution and heat transfer are much more efficient than with a heating cable.

It still heats when drilled through.

Unlike line systems (snake), carbon heating Film will still work and heat without any problems even if it is accidentally drilled through.

Into screed and directly under the floor covering

Thanks to the simple and exceptionally thin construction, the LARX Carbon Kit can be placed not only under the screed, but also directly under interlocked floor coverings (suitable for electric underfloor heating).

You think completely differently than others, and rightly so. The technology you use is efficient and, at the same time, of high quality. I came across LARX five years ago and since then you have been the exclusive supplier of smart technologies in all my real estate and industrial buildings.

Pavel Gelnar, Prachatice

Dear LARX, I would like to thank you for the quick response to my e-mail. Mr. Bartuška called me on Saturday morning and explained to me the marking (100W and 180W) on the Film that was delivered to me. I'm really glad that your company was able to react so quickly. The information I received was very useful. To my delight I found out that we don't have to change the Film. Thank you again and I wish you much success in your work.

Kind regards Pavel Jeřábek, Dačice
